ON INCREASING ROSES BY CUTTINGS OF THE ROOTS. 301 



folded into folio, which is to be stitched in coloured covers, making 

 fasciculi of five or six sheets each. A quantity of fine large post or 

 other writing paper, in half sheets, folio size, cut round the edges, is 

 also to be at hand. Let a number of narrow slips of different lengths 

 be cut from a piece of the same paper, and let some prepared 

 isinglass or dissolved gum be in readiness, together with a camel-hair 

 pencil. Take a dried plant, lay it upon a leaf of the fine cut paper 

 then fasten it down by means of a few of the slips, to which isinglass 

 or gum has been applied, laid across the stem and some of the 

 branches. Two or three slips are generally sufficient for a speci- 

 men. In this manner all the dried plants destined to form part of 

 the herbarium are treated. Write the name of each species on the 

 top of the leaf, and transcribe the notice respecting the place in 

 which it was gathered, &c, at the bottom. Then arrange the plant 

 according to system, and lay one between every two pages of the fas- 

 ciculi. The fasciculi are formed into bundles, by being laid alter- 

 nately up and down upon each other, as they do not lie conveniently 

 when the heads of the plants are all at the top of the bundle, because 

 the stalks and roots are thicker than the flowers. These bundles, 

 consisting each of ten fasciculi, may be covered by pieces of paste- 

 board tied by strings. The collection is kept on the shelves of a 

 cabinet made of pine wood, and to prevent depredations by insects, 

 of which the little Anobium castaneum is certainly principal, it is 

 only necessary to suspend two or three little bags, filled with cam- 

 phor, in the interior. This will be found quite effectual, and is much 

 more simple than the various other methods employed.

ON INCREASING ROSES BY CUTTINGS OF THE ROOTS, 



BY FL01IA. 



Having been advised to try the experiment of raising Rose trees 

 by taking cuttings off the roots, I did so, and found it to succeed 

 admirably. The mode I adopted was as follows : — The first week 

 in March I took some of the long, thick, and fleshy looking roots 

 of my English and French Roses, and cut them into pieces about 

 three inches long. I then smoothened the surface of a border in 

 front of a ueach wall, upon this I laid the roots flat, at about six
